figure this ou????????

[e30huh]

Fresh 2.7i swap and car missing and car running like it's missing. Idle fine, just missing like a like a school boy without his porns.

new head, new plugs, wires, cap, rotor. I have spark on all the wires (test with a screw driver), but cylinder 4 is not engaging. when car is running i pull the wire from #4 and no change. So, i swap wire #3 with #4 to test if it's a bad wire. But still no change. I have compression on #4 cylinder (158). Could it be a bad cap? just changed it 2 months ago. any inputs is greatly appreciate it.

Captain Obvious says "if it isn't spark then it must be fuel." Make sure that the #4 injector is getting power and try swapping it with another in the rail and see if the problem follows the injector. Then if no luck make sure the ground wire isn't broken (it goes to a splice then to the Cyl. 4-6 fuel injector pin on the DME.)

i am getting spark to the wire and plugs, pulled the plug and it's kinda shiny oily residue, not much

Mr. Visser,

you are da man, pick-n-pull used injectors at the yard. replaced and no more missing. thank you. i did have 12v across the injector rail. time to bounce my 5k tach off the chart.
